MAGAZINE FlRE-ARM.

SPEGIFICATION forming part of Letters Patent No. 290,393, dated December 18, 1.888.

27, 1883. (No model.)

To aZZ whom it may concern Be it known that 1, ANDREW Bunonss, a citizen ofthe United States, residing at Owego, in the county of Tioga and State of New York, have i nvented certain new and useful Improvements in Magazine-Guns, of which the followin g is a specification, reference being bad therein to the accompanying drawings.

My invention relates to magazine lire-arms; and it consists in certain details of construction and combinations of parts hereinafter more fully set forth.

The object of my invention is to produce a gun of simple construction, which may be easily operated, and of superior strength.

Figure l is a longitudinal section of the breech mechanism of a magazine-gun, showing some features of my invention. Fig. 2 is a similar view, showing other features of inven tion. Fig. iijis a similar view, showing additional features; of my invention. Fig. 4 is a modification, in which the working parts are operated-by the ordinary guard-lever. Fig. 5 is a cross-section, showing face of a bolt and carrier.

Similar letters of reference indicate corresponding parts.

The brace ii is here operated by a handpiece, S, below the barrel, and which connects with the brace by means of a rod, R. which, passing between the sides of the carrier, engages by a pin, 1', a diagonal slot in said brace. The pin 2' is guided to move longitudinally with the bolt by p rejecting into the slot 0* in said bolt. The brace 13 is held up in the bolt by guide 3 which is formed in the frame to hold the swinging end of the brace up in the bolt after it leaves the pin 1, and the tiringpin is withdrawn by the brace swinging up and coming back against its projection f. The rod ll. works in a slotted opening in the forearm, which is closed by the extension S" of the slide 5, which moves over and covers the said slot on the outside of said fore-arm and frame.

Fig. 9

n shows a modification'of Fig. 1, with additional parts. The brace B locks the bolt in. the some manner against the pin P; but in lieu the diagonal slot, I connect the rod It to the brace by the link L, and engage the firing-pin by the rod R, to withdraw said pin. The brace B is provided with a projection, b, which, as the brace is raised to unlock the breech, engages a projection, I), in the frame to start back the bolt. The ejector 13 consists of a slotted and hollow springpin set diagonally in the face of the bolt, which is stopped positively by the pin 0" in the frame when the bolt reaches near its rearward limit. The car rier is raised by the projection 1% on the reciprocating rod B, said projection also forcing the carrier down when in its forward position. The rod It is also provided with a projection,

t, to engage in a groove, 11, inside of the split carrier to force the sides of the carrier apart to admit a cartridge, and also to raise the carrier a little, as the rod recedes, to stop the magazine. The rod It is attached to the hand-slide S by a pin, and is slotted to allow said slide to follow the bottom of a tapering lore-arm. The rod R is guided longitudinally in the frame by engaging the guide g, or by attachment to the iiringpiu.

Fig. 3 shows another modification, in which the brace 13 is operated by a similar rod, 12,

and link but this rod extends rearward and is split to pass the hammer. The rear of rod it is attached to a lever, 1 whose fulcrum is in the frame, its other end being attached to a reciprocating slide, S, below the frame. I here show the trigger-guard as said slide, and attached to the lever by the link 11; but the slide may be independent oft/he guard, and the lever may be attached to the slide by a pin and slot or other means. The slide may be attached direct to the rod R; but I prefer to use the' lever to reverse the movement, so that the op orator may fire the piece as he pulls the slide rearward, and I here arrange the sliding trigger so it can only reach the sear when the slide has been pulled fully back and the breech thereby closed. The slide S has T projecting guides T T, w hich run in corresponding grooves in the guard-strap. I fix a removable knob. K, on the slide to be used when a better handhold is required.

In Fig. 3 I also show a lever, t, hung in the face of the bolt, which stops the c'artridde' in: the magazine when the breech is close. and which, striking the pin I when the breech is to lock in the opened, is thrown forward to start the cartridge into the chamber as it rises on the carrier, as shown in dotted lines in same figure. The projections t, extending inside the of the carrier, serve to expel the extracted shell as the carrier rises, and the lace and sides of the bolt have grooves t for said projections 15 to enter as the bolt closes. The upper tang has a raised portion, J3, to cover the upper end of the lever F.

Fig. 4 shows a further modification, in which I operate the brace 1% by a gnardicver, G, and arrange the lock in the belt of the gun. The brace B is hung in the bolt, as before, to lock it against the pin P. The brace split vertically at its rear to admit the end of the lever G and the roller 0, and the hole in the brace for the pin r is slightly slotted to allow the lever to raise the brace. As the brace rises, the roller 0, engaging the inclined faccf of the tiring-pin, (which is fixed in the hammer or thumb-piece IL) forces it back until the dog or sear h falls behind the notch h to cock the piece, by which tiniic the brace will have risen above the locking-pin and the bolt will be free to move rearward by force of the lever operating upon the brace B", and will close by the same moans upon the return movement of the lever, and the pull of the trigger will. force up the spring-pin h, as shown in Fig. 4-, to raise sear 1. from its notch 71. in the bolt to release the hammer. I furnish the thumb-piece H with a set-screw to regniate the engagement of the soar in its notch, and thereby regulate the force of the trigger-pull.

The sides of split carrier (1 are arranged to spring together and hold the cartridge tin-ward by an interior inclined abutment, i, Fig. 4, when the breech closed, and a spring-pawl, d. is hung in the bottom. of the bolt, with a forward projection, d, to strike the frame when the bolt is closed, to retire its rear end into the bolt, but as soon as the bolt starts back the pawl springs down to engage the llangc olthc cartridge and l'orceitback through the narrow inclined part 2, and thereby spread open the carrier. as seen in Fig. 5, (which shows the face ol'bolt and carrier,) and pull the cartridge back with the bolt until the cartridge flange lalls down the depression 0 of the carrier, which releases it from the pawl and allows the bolt to move back from over it, and the pawl coming in contact with the inclined top of pin l. rides over it.

The brace may be made to loch against the top of the frame by a reversal of parts similar to that shown in my application of the 12th of July, 1883. or the brace operated laterally side of the frame, as in said application, by mechanism, as here shown, all within the frame.

The lochirig-shoulder shown consists ol' a pin, 1, passing through the frame and held from. turning by a spline or any ordinary means, and a part of said pin. is cut away to present a greater bearing for the brace to lock against. hen the pin I is removed, it leaves an opening through which the pin 0' may be inserted to couple the parts to the brace, or removed when taking the works apart.

it will be seen that I bend or curve the rod or lever that works the brace around the lock ing-pin. This may be avoided by making the locking-shoulder as a mere projection inside of one or bot h sides of the frame. This leaves the center open for the operating rod or lever to pass. For greater strength I prefer to make the locking-brace the full width of the bolt.

I. do not herein claim all the mechanism shown in the drawings and described in the specification above, as parts of the device and modifications are described and claimed in two applications filed by me November 17, 1883.

What I do claim in this application is- 1. A reciprocating'bolt, a locking-brace pivoted therein adapted to bear against an abutmentin the frame, as described, a link pivoted to said lockingbrace, a draw-rod connected to said link, and a reciprocating handle beneath the frame connected to said draw rod, all the elements in combination, substantially as stated.

2. A reciprocatingbolt, alockingbrace piv oted therein and adapted to bear against an abutment in the frame, as described, alink pivoted to said lockingbracc, a draw-rod piv otally connected to said link and extending l'orward, and a sliding sleeve connected with the front portion of said draw-rod, all conibincd so that the reciprocation of the sleeve operates the bolt through the intermediate mechanism, substantially described.

' 3. The combination, with a breech-bolt, its locking devices, and a reciprocating rod, R, 01' a slotted t'ranic, through which said rod extends, the sleeve connectedthereto, as de scribed, and the sleevc-cxtension S, which covers said slot in the frame, all substantially as and for the purposes set forth.

4. The combination, with a reciprocating boll, a locking-brace pivoted therein, a link. connected to said brace, and operating mechanism, substantiall as described, connected to the link, of a removable pin, as 1, which extends through the frame and l'ormsan abutment l'or the locking-brace, all substantially as stated.
